Inverted Cone System

Removable and reusable system for quick and convenient low-pressure connections

Pressure rated up to 250psi (17 bar)

For 1/16”, 1/8” or 3/16” OD and metric sizes 2.0, 2.5 or 3.0mm OD semi-rigid tubing e.g. PTFE, ETFE, FEP

For flat-bottom ¼”-28 UNF, M6 or 5/16”-24 UNF ports

Use with Omni-Lok™ compact head or Click-N-Seal™ self-torquing nuts.

Omni-Lok™ inverted cones provide a simple, easy to use low-pressure connection. Only the ETFE cone is in the fluid path. No tools are required to assemble a flangeless fitting quickly and economically - just slip the fitting nut and the ETFE cone over the tubing and screw into the port. None of the parts are permanently attached to the tubing, so both fittings and inverted cones can easily be removed and re-used. A recess in the fitting houses the inverted cone, allowing maximum thread engagement with the port ensuring the system stays sealed up to 250psi (17 bar) pressure even in shallow PTFE ports.




Omni-Lok™ nuts

Omni-Lok™ compact head fitting nuts, in glass-filled

polypropylene, are available in a range of different colors for

easy line identification. Other options are a longer length nut

for applications where accessibility is an issue and standard

head nuts in PEEK™ for higher temperatures.



Click-N-Seal™ nuts

Click-N-Seal™ offers a unique system for hand-tight fittings. As the fitting is tightened, the resistance of the cap increases until the correct torque is reached; at which point, the cap clicks. The user is able to hand-tighten the fittings without tools or guesswork and be confident that the fitting is properly seated, creating a secure seal. The fitting can be unscrewed and reused.
